风电集群紧急功率控制方法研究
摘要：在调度中心要求风电集群紧急切功率时,需优化协调分配多个风电场的功率切除量。本文首先分析了风电场紧急功率切除的方式,进而提出了基于切场组合、基于风电场切机、基于切场与场内切机相结合和基于风电场累计有功功率切除量排序的4种不同的紧急切功率分配算法;其次以分配偏差量、风电场切场数等5个指标的加权组合构建综合评价指标以评估各算法的性能;最后以某实际风电集群为例,验证所提算法的有效性。分配结果和综合评价指标值表明4种分配算法都有各自的适用范围,其中基于风电场累计有功功率切除量排序的方法综合指标值最小,适用范围最大。
Abstract:When it is required to cut active power among wind farms in emergency situation, the coordination among wind farms is needed to allocate power cut amount. In this paper, the active power cut mode of wind farms is analyzed firstly, and four kinds of power allocation algorithms are proposed based on combination of cut wind farms, cut generators in wind farm, the combination of cut wind farms and cut generators in wind farm, and the ranking of accumulative active power cut amount in wind farm. Then, a comprehensive evaluation index is set up by weighted combination of five indicators, such as distribution deviation and the number of cut wind farms, to evaluate the performance of each algorithm. In the end, an actual wind power cluster is used as an example to verify the validity of proposed algorithms. Distribution results and comprehensive evaluation index values show that four kinds of allocation algorithms have different application scopes, in which the algorithm based on the ranking of cumulative power cut amount in wind farms has smallest comprehensive evaluation index value and the widest application scope.
